According to the present invention, a holey-plate material for absorbing and blocking sound is a holey-plate material having embossed portions formed thereon. Punched groups, which are formed in such a manner that a plurality of punched holes with diameters in at least two kinds are gathered, are formed at the holey-plate material while having a predetermined pattern. The punched groups form virtual regular hexagonal patterns in such a manner that a plurality of punched holes are gathered, and the regular hexagonal pattern are arranged to form a honeycomb structure. The holey-plate material for absorbing and blocking sound is able to absorb and block sound waves with various frequencies.
